Description
Technical Field
[0001] The utility model belongs to the technical field of non-negative pressure water supply equipment and relates to a direct-connection non-negative pressure water supply equipment. Background Art
[0002] Non-negative pressure water supply equipment is a pressurized water supply unit that is directly connected to the municipal water supply network and is a secondary pressurized water supply device that provides water supply in series based on the residual pressure of the municipal network to ensure that the pressure of the municipal network is not less than the set protection pressure. The core of the network superimposed water supply equipment is how to prevent the generation of negative pressure during the operation of the secondary pressurized water supply system, eliminate the impact of the unit operation on the municipal network, and achieve safe, reliable, and stable water supply without affecting the water use of nearby users. Non-negative pressure water supply equipment plays an important role in the water supply system. It can ensure stable water pressure and meet the water volume requirements of each pipeline. If the non-negative pressure water supply equipment cannot maintain uniform pressure supply in multiple pipes, it may cause a series of problems.
[0003] First, uneven water supply pressure can cause excessive or insufficient water pressure in some pipes. Excessive water pressure may cause safety hazards such as pipe rupture and water hammer, while insufficient water pressure may lead to insufficient water supply, affecting the normal water use of users, especially during peak water use periods, which may cause insufficient water pressure in some floors or areas, causing inconvenience to users.
[0004] Secondly, uneven water supply may also affect the equipment of the water supply system. For example, the water pump may be damaged due to working under abnormal pressure for a long time, resulting in shortened life or reduced performance. In addition, uneven water supply may also cause other problems in the system, such as cavitation, noise, etc. These problems will not only affect the performance of the water supply equipment, but also cause additional damage to the equipment.
[0005] Furthermore, for the entire water supply system, non-negative pressure water supply equipment cannot maintain uniform pressure supply in multiple pipes, which may lead to a decline in the overall performance of the system. The water supply system is a whole, and each part is interrelated and affects each other. If the water supply pressure of a certain pipeline is unstable, it is likely to affect the normal operation of the entire system.
[0006] In addition, for water supply companies, the inability of non-negative pressure water supply equipment to maintain uniform pressure supply in multiple pipes may affect the quality and quantity of water supply, thereby affecting the company's economic benefits and social reputation.
[0007] In summary, the inability of non-negative pressure water supply equipment to maintain uniform pressure supply in multiple pipes is a problem that cannot be ignored. Therefore, there is an urgent need for a direct-connected non-negative pressure water supply equipment to solve the above problems. Utility Model Content
